Kubo Utamaro is one of Shuriken School's three teachers and one of the supporting characters of the animated series, Shuriken School.
When he is one of the three teachers at Shuriken School, Kubo is in charge and teaches boring theory lessons and has been madly and desperately in love with a crush on Kita. He also dreams of being principal of Shuriken School one day (that was to replace Principal Sensei).
He is terribly boring, methodical, organized, strict and well-disciplined.
He is slender with fair skin, black hair and five mustache-like dots on his upper chin. Also, he also wears a orange suit-jacket with a black tie and white-long sleeved shirt, black pants and brown business shoes.
- Kubo is voiced by Maurice LaMarche who provided the voice of Daisuke Togakame, Naginata and Zumichito and also the voice of Etno from Space Goofs and Rintindumb from the series of the same name.
